Teacher's Moldy Bread Experiment To Teach Kids The Importance Of Washing Your Hands

September 20, 2017

This is a shot of the experiment conducted by high school (high school!) Health Occupation teacher Donna Gill Allen while teaching her class about germs and how they spread. I imagine a lot of kids learned an important lesson from this experiment. And that lesson is if you're going to make a sandwich with dirty hands, eat it right away and don't put it in a bag or it will get gross.

Thanks again to Jody, who agrees life is too short to care about not eating off the floor.

    I call BS. This caught my attention when a teacher posted the same experiment with no results. I wouldn't have expected much results myself. Kids have germs on their hands, rarely do they have mold. The only thing that would create this dramatic of a result is if the kids touched the bread with "dirty" WET hands.

    I think a better experiment for high schoolers would be to tell them that the moldy bread is promiscuous and caught all the cooties.

    Seriously this is neat for elementary and maybe middle school kids... in the 50s. High school now? How about we teach them that the human body contains 90% microbial (essentially non-human) genetics? That our immune system, digestion, and overall health depends upon a diverse microbiome. And all those fucking antibiotics your doc gives you for every sneeze because you whine like a bitch about it, is RUINING EVERYTHING.

    Ahem. I might be a lab tech.

    What kills me are antibiotics given/asked for for viral infection... I mean, c'mon.

  • Doog

    This. So much this.

    I can almost understand a person asking for them if they are ignorant about what both antibiotics and viruses are/do, but even then the doctor should have a rational conversation with the individual informing them of their ignorance. A doctor actually prescribing them, asked for or not, is unacceptable and recklessly crazy stupid.

    People really need to become more informed, one way or another, for the good of all of mankind.

    Why did the third piece of bread get a completely different set of variables? The "Controlled" and "clean" breads get handled by one person the other bread gets handled like a cheap hooker in an orgy. The Scientific method was not followed here, this study would never be published.

  • Doog

    Exactly. Let all the kids handle the bread after washing their hands. Something tells me that this was not done for a reason. Either way though this is about as scientific as my anecdotal research into how many drinks it takes to make me 'feel' intoxicated regardless of time or type of drink.

    Speaking of, I believe I'm close to a breakthrough. I mean I'm at about the same amount of drinks as yesterday and I might be starting to feel something.

    Now do another with clean hands and a little bit of moisture to show how the bread already had mold spores on it and it'll grow anyway

  • Bling Nye

    For sure; spoilage organisms don't really cause illness and pathogenic organisms don't really cause spoilage. While I totally agree with you about that, it's still a good "ah ha" moment of learning for the kids.

    ...until I just read it was in high school and not elementary school like I'd assumed. WTF? High schoolers should be streaking agar plates FFS, not playing with goddamn bread. :/

  • Jenness

    I too am horrified this is a HS experiment. Ever since 9/11 the entire education system purposefully handicapped our youth it seems.

  • Forblat

    Oh noooo I thought it was little kids!
    Still hopefully a learning moment anyway :-\

  • sizzlepants

    Holy crap! I didn't pick up that detail first time I looked at this either (I just read the image).

    We learned about mold and bread in grade 2.

    I know the public education system has been in decline for years now but holy hell that this needed to be taught to high school students is just pathetic.

    *when you find out your 6 year old has been washing his hands WITHOUT soap for the past 2 months*

  • FearlessFarris

    I'm always shocked by people in public restrooms who wash without soap. In a way, that's got to be worse than not washing at all.

  • Draco Basileus

    I'm always shocked by people in public restrooms who DON"T WASH THEIR HANDS AT ALL!

    I'm looking at you, Mr. Fancy Business Suit in Suite 1350. Just because you enjoy fondling your peen in bathroom doesn't mean that I have to "enjoy" it too by touching the same door handle on my way to freedom.

  • Brock

    "Just because you enjoy fondling your peen in bathroom"
    Do you touch your penis to pee in public bathrooms? That's as gross as not washing hands (maybe more). You just touched the bathroom door to enter, and everything else in public, then rub it all over your penis?!?
    Hate to be your lover...

    Just let it fall out of the pants and push. If you need aim, use your hips. Don't be afraid to touch it, but reserve that action for when you're at home people.

    It's best to wash hands after you pee in public because of many other things (splash, handles, etc). It's not supposed to be because everyone is fondling themselves...

  • Draco Basileus

    I think you missed my point. I was referring to the a-hole in my office building who takes a piss and then walks out of the bathroom without washing his hands. Even though I wash MY hands when I'm finished, I still have to get out of the bathroom by grabbing the handle that this dipshit just smeared his junk butter on.

  • Doog

    I'm not even sure what to say about this comment, except that it's rather stupid (imo).

    For one you can handle a door with one hand and handle your junk with the other hand, easily. Like, both actions only require one hand typically.

    Also, unless you're smaller than average you're probably going to have to touch your penis or you'll wind up peeing down onto yourself. I suppose you could provide yourself a guiding hand using your underwear as a barrier, but you probably should be more comfortable touching yourself than that.

    I'm honestly not trying to be as insulting as I'm sure I've already come across, but your comment reads like something a female would write with zero knowledge of the male bathroom experience.

  • Draco Basileus

    See my reply to Brock

  • Doog

    Oh I totally understood the point you were making. There's a guy where I work that does the same thing, luckily everyone knows and no one shakes his hand (which he's really into for some reason). It really just made his comment weirder since it wasn't really on-topic. It seemed like he was just looking for a way to make a statement about how gross people are for touching themselves while using the bathroom.

    Also, kudos on the disgustingly humorous 'junk butter'. It's been a while since two words sitting side by side made me as uncomfortable as those two just did.

  • Bling Nye

    Better than not washing at all, since mechanical action of rubbing the hands plus running water can remove some stuff, but still very gross.
